Warm With Widely Spaced Showers

Wed, 10/08/2014 - 15:04

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: Not much to show on radar this afternoon; the sky is partly sunny and temperatures are mostly in the low to mid 80s. We do note a few strong storms on the Mississippi River south of Memphis; those could creep into Northwest Alabama early tonight….

If the storms do hang on and move through North Alabama tonight, they could be fairly strong; SPC maintains low end 5 percent severe weather possibilities.

TOMORROW/FRIDAY: The weather stays warm with highs in the mid 80s; upper 80s are possible in spots. That is about ten degrees above average for mid-October in Alabama. A warm front will push northward through here tomorrow and could trigger a few showers or storms, but they should be widely spaced.

Then, on Friday, a cold front will sag down into Tennessee and become stationary Friday night somewhere near or just south of I-40. Scattered showers and storms are possible Friday afternoon and Friday night; they will be most numerous north of U.S. 278 (Hamilton to Cullman to Gadsden), but a few are possible as far south as I-20 (Tuscaloosa to Birmingham to Anniston).

THE ALABAMA WEEKEND: South of Birmingham, the weekend will be warm and dry with highs in the 80s. But, from Birmingham north, we will mention a chance of scattered showers and thunderstorms both days as the front will hang tough just the north of the Alabama/Tennessee state line. The chance of any one spot seeing a shower or storm along and north of I-20 both days is about one in three.

NEXT WEEK: A strong upper trough will bring a much better chance of rain and storms statewide by Monday afternoon and Monday night; there might even be a few strong storms involved with good upper support. Then, cooler and drier arrives Tuesday through mid-week. More details are on the Weather Xtreme video along with all of the maps and graphics.

FOOTBALL WEATHER: For the high school games tomorrow night; a few isolated showers are possible during the first half, otherwise mostly fair with temperatures falling through the 70s. Then, on Friday night, widely scattered showers and storms are possible from Birmingham north during the games, with dry conditions south of Birmingham. Temperatures will fall through the 70s.

On Saturday, Auburn will take on the Mississippi State Bulldogs in Starkville (2:30p kickoff). The sky will be partly sunny with a kickoff temperature near 85 degrees; just a slight risk of a brief shower or storm during the game. Temperatures will fall to near 80 degrees by the final whistle.

Alabama will be on the road as well; they play Arkansas at Fayetteville (5:00p kickoff). Showers and storms are a good possibility, mainly during the first half of the game. The temperature will drop from near 65 degrees at kickoff, into the 50s by the fourth quarter. Take the rain gear.

UAB will celebrate homecoming Saturday; the Blazers host North Texas (2:30p kickoff) at Legion Field. The sky will be partly sunny, and temperatures will fall from near 85 degrees at kickoff to around 80 by the fourth quarter. We can’t rule out a brief passing shower or thunderstorm.

NATIONAL SHRIMP FESTIVAL: Delightful weather for the big event at Gulf Shores Thursday through Sunday. Mostly sunny warm days, fair nights. Highs in the 80s, lows in the 60s.

TROPICS: All is quiet for now across the Atlantic basin, and tropical storm formation is not expected through Friday.

Warm Days Through The Weekend

Wed, 10/08/2014 - 06:22

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

FULL ECLIPSE OF THE MOON: It has been an early morning of sky watching; totality started at 5:25a CT. Here is a look from Helena… photo from @charnita

Our friends up in Northeast Alabama aren’t able to see the eclipse due to clouds and scattered showers; the clouds thin out as you work your way to the south. The moon has now set and is below the horizon at daybreak.

THE DAY AHEAD: For much of Alabama, the day will be warm and dry with a partly sunny sky and a high in the 80s. The upper trough over the eastern U.S. is lifting out, and is being replaced by an upper ridge centered on the Gulf Coast. However, the high resolution HRRR model does show a band of showers and storms moving into North Alabama late this afternoon and early tonight, and we will insert that potential into the forecast. The highest risk of a shower or storm will be north of I-20 (Tuscaloosa to Birmingham to Anniston).

TOMORROW/FRIDAY: Warm is the word… highs will be in the mid to upper 80s, about ten degrees above average for early October. A warm front lifting north tomorrow afternoon could kick off a few scattered showers; like recent days the highest risk of a shower will be north of Birmingham. Then, on Friday, much of the day will be dry, although a few showers and storms could creep down into North Alabama late in the day or Friday night ahead of a cold front over Tennessee.

THE ALABAMA WEEKEND: The front over Tennessee will become stationary. The southern half of the state will remain warm and dry, but we will mention the risk of scattered showers and storms over North Alabama, especially north of Birmingham. The weather stays warm with highs in the mid 80s.

Showers and storms should increase Monday of next week as an upper trough approaches from the west; see the Weather Xtreme video for maps, graphics, and more details.

FOOTBALL WEATHER: For the high school games tomorrow night; a few isolated showers are possible during the first half, otherwise mostly fair with temperatures falling through the 70s. Then, on Friday night, most stadiums will be dry with only a slight risk of a brief evening shower. Again, temperatures will fall through the 70s with a mostly fair sky.

On Saturday, Auburn will take on the Mississippi State Bulldogs in Starkville (2:30p kickoff). The sky will be partly sunny with a kickoff temperature near 85 degrees; just a slight risk of a brief shower or storm during the game. Temperatures will fall to near 80 degrees by the final whistle.

Alabama will be on the road as well; they play Arkansas at Fayetteville (5:00p kickoff). Showers and storms are a good possibility, mainly during the first half of the game. The temperature will drop from near 65 degrees at kickoff, into the 50s by the fourth quarter. Take the rain gear.

UAB will celebrate homecoming Saturday; the Blazers host North Texas (2:30p kickoff) at Legion Field. The sky will be partly sunny, and temperatures will fall from near 85 degrees at kickoff to around 80 by the fourth quarter. Only a small risk of a shower during this game.

NATIONAL SHRIMP FESTIVAL: Delightful weather for the big event at Gulf Shores Thursday through Sunday. Mostly sunny warm days, fair nights. Highs in the 80s, lows in the 60s.

TROPICS: A disturbance over the far southwest Caribbean remains disorganized, and tropical storm formation is not expected this week in the Atlantic basin.

Warm October Weather

Tue, 10/07/2014 - 15:50

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: Showers and storms that were over the Tennessee Valley region of North Alabama earlier today have moved out of the state, and there is basically nothing on radar at mid-afternoon; quite the contrast to the radar images we had at this time yesterday. Temperatures are generally in the low 80s with a partly sunny sky.

REST OF THE WEEK: The large scale upper trough that was over the eastern U.S. will weaken and lift out, and a ridge of high pressure aloft will begin to build, meaning unseasonably warm weather. We expect highs mostly in the mid 80s, although some spots could reach the upper 80s; each day will feature a mix of sun and clouds.

There will be enough moisture for a shower or two each day in spots, but they will be pretty widely spaced. The GFS hints the best coverage of showers or storms will come on Thursday as a warm front lifts northward. Even then it will a “hit and miss” proposition. Many communities will be dry tomorrow through Friday.

THE ALABAMA WEEKEND: A cold front to the north will stall out over Tennessee. On Saturday, the best chance of showers will be close to the Tennessee border; most of the state will be warm and dry with a high in the 80s. The front will sag a little southward Sunday and Monday, with a better chance of showers and storms on these two days. But, they will be scattered in nature, and some places won’t see very much rain. The high Sunday will be in the low to mid 80s, but Monday’s high will be closer to 80 degrees.

Keep in mind October is our driest month of the year, so getting a good, widespread, soaking rain event this time of the year can be difficult. Synoptic scale rain events increase in November and December as we get into the late fall tornado season.

FOOTBALL WEATHER: For the high school games Thursday night; a few isolated showers are possible during the first half, otherwise mostly fair with temperatures falling through the 70s. Then, on Friday night, most stadiums will be dry with only a slight risk of a brief evening shower. Again, temperatures will fall through the 70s with a mostly fair sky.

On Saturday, Auburn will take on the Mississippi State Bulldogs in Starkville (2:30p kickoff). The sky will be partly sunny with a kickoff temperature near 85 degrees; just a slight risk of a brief shower or storm during the game. Temperatures will fall to near 80 degrees by the final whistle.

Alabama will be on the road as well; they play Arkansas at Fayetteville (5:00p kickoff). Showers and storms are a good possibility, mainly during the first half of the game. The temperature will drop from near 65 degrees at kickoff, into the 50s by the fourth quarter. Take the rain gear.

UAB will celebrate homecoming Saturday; the Blazers host North Texas (2:30p kickoff) at Legion Field. The sky will be partly sunny, and temperatures will fall from near 85 degrees at kickoff to around 80 by the fourth quarter. Only a small risk of a shower during this game.

NATIONAL SHRIMP FESTIVAL: Delightful weather for the big event at Gulf Shores Thursday through Sunday. Mostly sunny warm days, fair nights. Highs in the 80s, lows in the 60s.

TROPICS: A disturbance over the far southwest Caribbean has come potential for slow development by the weekend. Some global models move this up into the southern Gulf of Mexico next week; see the Weather Xtreme video for the maps, graphics, and more details.

Scud or Cold Air Funnel?

Tue, 10/07/2014 - 07:13

I received literally hundreds of images of this creepy cloud over Cullman late yesterday afternoon…

No doubt this was not a tornado, but is it a scud cloud? Or, a cold air funnel?

Scud clouds can look like a tornado or funnel cloud, but they are harmless. Scud clouds are not attached to large-scale storm rotation. They are caused by cold air outflow interacting with warmth ahead of the storm. This causes air to rise and condense. While these clouds often hang low under the base, they don’t indicate anything other than wind blowing out of the storm.

Cold air funnels are most commonly observed in the vicinity of a closed off, cold-core mid level low, or upper trough (there was a large scale upper trough over the eastern U.S. yesterday with very cold air aloft over Alabama). The cold air aloft associated with these features is how cold air funnels get their name. However the cold air aloft only provides instability for convection, it does not govern how the funnel clouds form. The upper rotation associated with the upper low provides an environment rich with vorticity, or “spin”. It is believed that within this spinning environment, localized areas of higher vorticity exist. Thanks to the cold air aloft, updrafts are able to develop and stretch the vorticity in the environment. Stretching of vorticity creates a column of rapidly-spinning air, and it is believed that this may lead to the development of a funnel cloud. Cold air funnels come from high based storms, and rarely touch the ground.

The NWS does not issue tornado warnings for cold air funnels.

From all of the reports received, many said there was no rotation. Some did report slow, erratic rotation. Sure seems like this was scud to me. But, we will keep looking at data and reports.

Bottom line is that this was not a tornado, and there was never danger of a tornado from the storm due to the high based nature of the thunderstorm (LCL heights over 1,000 meters). Hail was the big issue, and there was plenty of that…

Higher Risk Of Storms Stays North

Tue, 10/07/2014 - 06:18

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: The last batch of storms has moved out of Northeast Alabama at daybreak, and the weather is relatively quiet across Alabama with temperatures generally in the 60s.

LATER TODAY: The cold core, upper trough remains over the eastern third of the nation, and another wave rotating through the base of the trough is expected to kick off more showers and storms over North Alabama later this morning, but the high resolution HRRR model hints those storms will be mainly over the Tennessee Valley (below is model output valid at 11a CT)…

The bottom line is that the risk of rain now looks small today for places like Tuscaloosa, Birmingham and Anniston… highest risk of a shower or storm will be along and north of U.S. 278 (Hamilton to Cullman to Gadsden).

We will see a mix of sun and clouds, and temperatures should reach the low 80s this afternoon.

REST OF THE WEEK: A relatively moist air mass will remain in place, so we can’t rule out a few widely scattered showers or storms tomorrow and Thursday, but widespread rain is not expected. The sky will be partly sunny with a high up in the mid 80s.

Friday looks generally warm and dry; temperatures will rise into the mid 80s again, with potential even for upper 80s in a few spots. A cold front to the north will bring a risk of showers and storms to Kentucky and Tennessee, but new model guidance hints that front will stall out around I-40 in Tennessee, well to the north of Alabama. This means there is a pretty good chance we won’t have to deal with rain for the high school football games Friday night, with the exception of stadiums up near the Tennessee border.

THE ALABAMA WEEKEND: With the front stalling out over Tennessee, it looks now like the weekend will be mostly dry and warm for North/Central Alabama. Showers are possible mainly over the Tennessee Valley of far North Alabama; afternoon highs will remain very warm for October, with mid 80s likely Saturday and Sunday. The GFS does show the front nudging down to the south Monday of next week, with a better chance of showers and storms down to I-20, but the activity will be scattered. See the Weather Xtreme video for the maps, graphics, and more details.

TROPICS: All remains quiet, and tropical storm formation is not expected this week. The GFS continues to show some Gulf of Mexico mischief in about a week, but that remains to be seen if anything can actually develop there.

NATIONAL SHRIMP FESTIVAL: Perfect weather in Gulf Shores for the big event Thursday through Saturday. Sunny warm days, fair pleasant highs. Highs in the 80s, lows in the 60s. Could not be better.

    Evening Update

    Mon, 10/06/2014 - 18:43

    We continue to monitor a few strong and locally severe storms across Alabama this evening. All storms this afternoon and evening have been confined to the northern third of the state and north of the Intestate 59 corridor. Storms today have been pulsing up in intensity for a few minutes but then pulsing down. Very strong and robust updrafts have been occurring with these storms and these storms have been producing very large hail in areas they have affected. Numerous reports of hail up to the size of golf balls across portions of Wintson, Walker, and Cullman counties. Storms continue to move off towards the east to northeast rapidly.

    The SPC maintains much of North Alabama under a slight risk for severe weather through the overnight hours (areas outline in green above). Looking at the overall dynamics in the area below, there is ample CAPE in portions of Arkansas, Tennessee, and northern Mississippi. We are waiting to see if additional storms develop back to the northwest, and these will be watched carefully as instability remains robust in the areas outlined in the risk. However, as the sun sets, storm coverage and intensity should begin to diminish slowly as instability values decrease do to the loss of daytime heating. We should see storms last a few more hours, before winding down before midnight. Latest mesoscale discussion from the SPC suggest a severe weather watch will not be needed for this event across Alabama.

    Scattered Storms Through Tomorrow

    Mon, 10/06/2014 - 15:47

    An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

    RADAR CHECK: One strong storm earlier today developed over Calhoun County, producing small hail north of Anniston at places like Weaver; that storm is well into Georgia, and moving away. However, new storms have fired up over Northwest Alabama, and hail has also been reported in Marion County.

    The storms are moving east/northeast, and due to very cold air aloft (500 mb temperatures down to -15C), hail is very possible in the stronger storms for the next several hours. SPC maintains the standard “slight risk” of severe weather for North Alabama due to this potential. Storms should weaken later tonight as the air becomes more stable.

    TOMORROW: Another wave will rotate down the back side of the big upper trough over the eastern U.S., and we will need to keep the risk of scattered storms in the forecast. The high resolution NAM suggests the highest coverage of storms will actually come during the morning hours, but they are possible basically at any time during the day; the high will be in the 77-80 degree range with the sky occasionally cloudy.

    WEDNESDAY THROUGH FRIDAY: These three days will be warm with highs up in the low to mid 80s. We can’t rule out a shower or storm on any day, but they will be widely spaced, and mainly over the northern third of the state. An approaching cold front will push an organized band of showers and storms into North Alabama Friday night, but that front will stall out somewhere around the Alabama/Tennessee border.

    THE WEEKEND: The stalled front will be just north of here, meaning some risk of at least scattered showers and thunderstorms Saturday and Sunday, with the best coverage along and north of I-20. This won’t be a continuous rain, and not a “wash out”, but if you have outdoor plans just be aware some rain is very possible at times. Our highs will be in the 77 to 81 degree range. South Alabama looks mostly warm and dry for the weekend.

    See the Weather Xtreme video for the maps, graphics, and more details.

    TROPICS: The Atlantic basin remains quiet, and tropical storm formation is not expected this week. We do note there has been some consistency in the idea of a tropical system forming near the Yucatan coast in about 6-8 days, with a northward motion into the Gulf of Mexico. Way too early to know if this happens at all; see the video for more details.

    NATIONAL SHRIMP FESTIVAL: The weather could not be better for the big event at Gulf Shores; look for sunny warm days, and fair pleasant nights Thursday through Sunday with only a small risk of a shower Sunday afternoon. Highs in the 80s; lows in the 60s. Sea water temperatures are in the 78-81 degree range.

    WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. We will produce this week’s show tonight at 8:30 CT… you can watch it on “James Spann 24/7″ on cable systems around the state, or on the web here.

    Watch Possible for North Alabama

    Mon, 10/06/2014 - 15:30

    AREAS AFFECTED…TN…MS…AL

    CONCERNING…SEVERE POTENTIAL…WATCH POSSIBLE

    PROBABILITY OF WATCH ISSUANCE…40 PERCENT

    SUMMARY…ISOLATED TO SCATTERED SEVERE STORMS WITH HAIL APPEAR
    POSSIBLE ACROSS PARTS OF THE TN VALLEY INTO THIS EVENING. ACTIVITY
    BEGINNING TO DEVELOP ACROSS THE REGION WILL CONTINUE TO BE MONITORED
    WITH A WATCH POSSIBLE IF AN INCREASE IN STORM COVERAGE/ORGANIZATION
    IS NOTED.

    DISCUSSION…STRONGER DESTABILIZATION HAS OCCURRED ACROSS THE TN
    VALLEY IN RECENT HOURS AS CI CANOPY AND DEBRIS CLOUDINESS FROM
    EARLIER CONVECTION HAS BEGUN TO CLEAR THE AREA. SOMEWHAT MOIST
    SOUTHWESTERLY LOW LEVEL FLOW AND CONTINUED HEATING MAY BOOST MLCAPE
    ABOVE 1000 J/KG AS NEW STORM DEVELOPMENT OCCURS ALONG WEAK RESIDUAL
    BOUNDARY LEFT IN THE WAKE OF EARLIER STORMS. STRONGER MID-LEVEL
    FLOW…HEIGHT FALLS…AND COLDER AIR ALOFT WILL BRUSH THE REGION AS
    A POTENT SHORTWAVE TROUGH PASSES TO THE NORTH. THESE INFLUENCES MAY
    ACT TO PROMOTE ADDITIONAL STORM DEVELOPMENT OVER THE NEXT 1-3 HOURS.
    PRIMARILY UNIDIRECTIONAL SHEAR ON THE ORDER OF 30-40 KT WILL SUPPORT
    UPDRAFT ORGANIZATION/PERSISTENCE WITH A COUPLE OF SUPERCELLS AND/OR
    SPLITTING CELLS POSSIBLE. GENERALLY WEAK AND VEERED LOW-LEVEL FLOW
    SHOULD TEMPER ANY TORNADO THREAT BUT A COUPLE OF LONGER-LIVED CELLS
    COULD POSE A THREAT FOR HAIL. ACTIVITY TRENDS WILL BE MONITORED FOR
    AN INCREASE IN COVERAGE/INTENSITY WITH A WATCH POSSIBLE IF THESE
    TRENDS BECOME MORE EVIDENT.

    Moist Air Returns To Alabama Today

    Mon, 10/06/2014 - 06:29

    An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

    AT DAYBREAK: Still pretty chilly over Northeast Alabama this morning with low to mid 40s reported from Gadsden up to Fort Payne. We note over the weekend our Skywatcher at Black Creek, Vic Bell, dropped to freezing early yesterday (his low was 32), his earliest freeze on record. There was scattered frost across the colder valleys yesterday morning. Nothing on radar over Alabama as the new day dawns.

    THE DAY AHEAD: We are watching a line of showers and strong storms just northwest of Alabama…

    These showers will slowly weaken, but some of them will move into the northwest corner of Alabama this morning. These showers and storms are ahead of a spoke of energy rotating down the back side of the long wave upper trough over the eastern half of the U.S. And, that wave will bring the chance of showers and storms to North Alabama later today and tonight.

    STRONG STORMS? SPC has North Alabama, areas generally north of I-59, under the standard “slight risk” of severe weather for this afternoon and tonight; this risk extends west and north to Texas and Kentucky. Shear and instability values are somewhat marginal for severe weather in our state, but very cold air aloft, associated with the upper trough, seems to be the biggest flag, meaning the greatest threat will come from large hail, especially north of I-20 and west of I-65.

    The main window for stronger storms will come from about 2:00 until 9:00 p.m. We will watch radar trends closely.

    TOMORROW: Another wave embedded in the large upper trough will pass north of the state, and we will mention scattered showers and storms tomorrow, mainly north of I-20. The sun might peek out at times tomorrow, and the high should be in the 77-81 degree range. No “all day” rain.

    WEDNESDAY THROUGH FRIDAY: Wednesday and Thursday look relatively dry and warm. A few showers could fire up Thursday afternoon over North Alabama as isentropic lift increases over the state, but widespread rain doesn’t look especially likely for now. Afternoon temperatures will rise into the low to mid 80s on these days. Then, on Friday, a cold front will approach from the north. The GFS suggests a band of showers and storms could move into our state late Friday afternoon and Friday night. This could mean some rain issues for high school football games across North Alabama.

    THE ALABAMA WEEKEND: The front sags down into North Alabama, and becomes stationary as it will be parallel to the upper air flow. This means we will have the chance of a few passing showers and thunderstorms both Saturday and Sunday. The rain won’t be continuous, but you will need to be ready for occasional showers and possibly a thunderstorm if you have something planned outdoors. High temperatures over the weekend will be in the 75-79 degree range, about average for mid-October in Alabama. Probably not much sun.

    See the Weather Xtreme video for maps, graphics, and more details.

    TROPICS: All remains quiet across the Atlantic basin, and tropical storm formation is not expected this week. The hurricane season runs through the end of November, but generally after October hurricanes are not very common as the ocean water temperatures cool.

    GULF COAST WEATHER: The National Shrimp Festival is this Thursday through Sunday on the Alabama Gulf Coast… one of the biggest events of the year. The weather looks great, with mostly sunny days and fair nights; only a small risk of a shower Sunday. Highs will be in the 80s, and lows in the 60s. The sea water temperature at the Dauphin Island Sea Lab this morning has cooled to 72 degrees.

    WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40.

    Chilly Start But a Warm Afternoon

    Sun, 10/05/2014 - 07:43

    An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

    It was a chilly start to this Sunday morning with some light frost reported across the northeast quadrant of Alabama. Skywatcher Vic Bell at Black Creek reported a low of 32 degrees, his earliest freeze ever by about four days. With clear skies we should see the morning chill give way to a warm afternoon as highs climb into the middle 70s.

    The surface high will slide east and northeast of us Monday allowing a quick return of warm moist air to our west and northwest. This quick return along with a strong short wave moving through the trough situated over the eastern US will set the stage for possible severe weather in a fairly narrow band just to our north and northwest. SPC has outlined a slight risk area that encompasses places like Nashville, Memphis, Tupelo, Muscle Shoals, and Huntsville. CAPE and helicity values support the idea of supercell development. Cold air aloft will support a large hail threat while the shear also supports a tornado threat.

    The fast moving short wave will zip by Tuesday ending the threat of rain and storms. But the pattern remains challenging as we come under a brief period of ridging for Wednesday and Thursday before we have to deal with the remnants of Simon. The GFS suggests a weak disturbance, remnants of Simon, will move across the Lower Mississippi River Valley on Friday and Saturday bringing clouds and showers to Central Alabama. The moisture will stick around into Sunday before another short wave coming out of the Central Plains will bring an end to rain chances early into voodoo country.

    For beach goers, the weather looks dry for much of the week ahead with highs in the lower 80s and lows around 70. Gulf water temperature continues to be in the lower to middle 70s along the Alabama and Northwest Florida coastline.

    Looking into week 2, the GFS is sowing another substantial trough around the 14th/15th time frame with the potential for some tropical mischief. This is voodoo country after all. The trough over the eastern US remains the look out to the 20th.
